 I want to migrate BLE HRS peripheral sample to custom board with Raytac&amp;#39;s MDBT42-512KV2 (WLCSP nrf52832 used). The board doesn&amp;#39;t have external XTAL. 
 In sdk_config.h I set: 
 #define NRF_SDH_CLOCK_LF_SRC 0 #define NRF_SDH_CLOCK_LF_RC_CTIV 16 #define</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 28 Jan 2019 16:30:39 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/43060/migration-to-mdbt42" /><item><title>RE: Migration to MDBT42</title><link>https://devzone.nordicsemi.com/thread/168308?ContentTypeID=1</link><pubDate>Mon, 28 Jan 2019 16:30:39 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:675fcf13-9e55-4b96-88b6-cc0874658df6</guid><dc:creator>gaminn</dc:creator><description>&lt;p&gt;Not sure what the issue was, maybe rebuild helped.

&lt;p&gt;&amp;nbsp;So you have programmed the softdevice, right?&lt;/p&gt;
&lt;p&gt;I would recommend that you set NRF_SDH_CLOCK_LF_ACCURACY = 1; when you use the internal RC Oscillator.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Did you do any other changes to the project? Do you have a board header file that matches your custom board?&lt;/p&gt;
&lt;p&gt;If you are able to debug, can you try to define DEBUG in your preprocessor defines and set a breakpoint in the app_error handler to see whether any of the APP_ERROR_CHECK(err_code) receives an err_code != NRF_SUCCESS?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;If you have the possibility for monitoring the log (try to enable RTT logging, and watch the RTT Log using &amp;quot;J-Link RTT Viewer&amp;quot;. If you have DEBUG in your preprocessor defines it should print out where the application fails.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Edvin&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
